--- Comment #4 from Arturo Hoffstadt Urrutia <art...@hoffstadt.cl> --- Created attachment 157305 --> https://bugs.kde.org/attachment.cgi?id=157305&action=edit New crash information added by DrKonqi systemsettings (5.26.4) using Qt 5.15.7 Simply opening the System Settings > Appeareance > Global Theme > Window Decoration is enough to trigger the crash. It can be reproduced consistenly. One time by chance, my mouse was not over the Breeze theme thumbnail, and the Window Decoration was able to start. The Breeze Window Decoration thumbnail was empty, while the other window decoration worked. Also, I noticed that at the time this happened, the Window Decoartion switched to Plastik. -- Backtrace (Reduced): #4 0x00007f92c18b3e84 in KDecoration2::Decoration::shadow() const () from /lib64/libkdecorations2.so.5 #5 0x00007f92c1441a55 in KDecoration2::Preview::PreviewItem::hoverLeaveEvent(QHoverEvent*) () from /usr/lib64/qt5/qml/org/kde/kwin/private/kdecoration/libkdecorationprivatedeclarative.so #6 0x00007f92fae96d68 in QQuickItem::event(QEvent*) () from /lib64/libQt5Quick.so.5 #7 0x00007f92fd9aed12 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /lib64/libQt5Widgets.so.5 #8 0x00007f92fcca8278 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () from /lib64/libQt5Core.so.5 -- You are receiving this mail because: You are watching all bug changes.
